GE Multilin MMII-PD-1-2-120 Motor Manager
The GE Multilin MMII-PD-1-2-120 is a advanced motor management relay designed to provide comprehensive protection, monitoring, and control for medium to large AC motors. As part of the Multilin MM2 series, it integrates protection functions, real-time diagnostics, and communication capabilities to ensure reliable motor operation, prevent premature failures, and optimize maintenance in industrial applications.
This motor manager is engineered to handle diverse motor types and operational conditions, making it suitable for critical machinery in manufacturing, utilities, and process industries.
Core Protection & Monitoring Functions
Motor Protection
Includes overcurrent, overload (thermal modeling), phase loss/unbalance, ground fault, under/overvoltage, and locked rotor protection.
Real-Time Monitoring
Measures and records key parameters: current, voltage, power (kW/kVA), power factor, motor temperature, and operating time.
Control Capabilities
Supports motor start/stop control, programmable logic for interlocks, and remote operation via communication protocols.
Diagnostics & Logging
Captures fault records, trip history, and trend data to facilitate root-cause analysis and predictive maintenance.
Technical Specifications
| Parameter | Specification |
|---|---|
| Input Voltage | 120V AC (control power) |
| Current Sensing | Through current transformers (up to 5000A with appropriate CT ratios) |
| Communication | RS-485 (Modbus RTU), optional Ethernet (Modbus TCP/IP) |
| Outputs | 4 x Form C dry contacts (for alarms/trips), 2 x analog outputs (4-20mA) |
| Operating Temperature | -40°C to +70°C (-40°F to +158°F) |
| Enclosure Rating | NEMA 4X / IP66 (when panel-mounted with proper gaskets) |
Key Features & Benefits
- Adaptive Thermal Modeling: Uses motor load and ambient temperature to accurately simulate winding temperature, preventing thermal damage.
- Flexible Configuration: Programmable settings for motor parameters, trip delays, and logic sequences to match specific application requirements.
- Seamless Integration: Communicates with SCADA, DCS, or CMMS systems for centralized monitoring and control.
- Robust Design: Withstands harsh industrial environments, including vibration, humidity, and electrical noise.
User-Friendly Interface: Equipped with a front-panel display and keypad for local configuration, status checks, and fault viewing.
Typical Applications
Ideal for protecting and managing motors in:
- Pumps, fans, and compressors in water/wastewater treatment plants
- Conveyors and material handling systems in manufacturing facilities
- Mixers and agitators in chemical and pharmaceutical processes
- Crushers and mills in mining and mineral processing
HVAC systems in large commercial or industrial buildings
